Steel Grade

JIS G3456 carbon steel tubes are available in various grades, including STPT370, STPT410, and STPT480. These grades indicate the minimum tensile strength and yield strength of the tubes.

• STPT370: Minimum tensile strength of 370 MPa and minimum yield strength of 215 MPa.
• STPT410: Minimum tensile strength of 410 MPa and minimum yield strength of 245 MPa.
• STPT480: Minimum tensile strength of 480 MPa and minimum yield strength of 275 MPa.

Application

The JIS G3456 carbon steel tubes find application in several industries, including:

1. Heat exchangers: These tubes are widely used in the construction of heat exchangers for transferring heat between two fluids or gases.
2. Boilers: The tubes are suitable for use in boilers, where they carry high-pressure steam or hot water.
3. Superheaters: Superheaters in power plants require heat-resistant tubes that can withstand high temperatures, making JIS G3456 tubes an ideal choice.
4. Pressure vessels: The tubes are utilized in the construction of pressure vessels that handle high-pressure fluids or gases.
